To
execute
the
program,
instead
of
typing
RUN
80
or
GOTO
10,
you
need
only
to
press
the
~
key
and
then
the
letter
used
as a label.
In
the
above
example,
pressing
~
and
then
'B'
would
cause
'SECOND'
to
appear
on
the
display.
When
DEF
is
used
to
execute
a
program,
variables
and
mode
settings
are
affected
in
the
same
way
as
when
GOTO
is
used.
See
Chapter
8
for
details.
ReSerVe Mode
Another
timesaving
feature
of
the
PC-3
is
the
ReSerVe
mode.
Within
the
memory
of
the
PC·3,
47
characters
are
designated
for
"Reserve
Memory".
You
can
use
this
memory
to
store
frequently-
used
expressions,
which
are
then
recalled
by
a
simple
two-keystroke
operation.
NOTE:
You
store
the
strings in
the
ReSerVe
mode
and
recall
them
for
use in
the
RUN
and
PROgram
modes.
Try
this
example
of
storing
and
recalling a reserved string.
Switch
the
PC-3
into
ReSerVe
mode
by
moving
the
slide
switch
to
the
RSV
position.
Type
NEW,
followed
by
the
(ENTER)
key.
This
will clear
out
any
previously
stored
characters
in
the
same
way
NEW
clears
out
stored
programs
in
the
PROgram
mode.
Type
(SHIFT)
followed
by
'A'.
